  • Description: The combination of fungal pre-treatment with Trametes pubescens and anaerobic digestion were tested for the removal of chemical oxygen demand (COD) and phenolic compounds from wine distillery wastewater. The COD removal efficiency after fungal pre-treatment reached 53.3%. During digestion, pH buffering was achieved using CaCO3 and K2HPO4. This provided a stable environment inside digester for efficient and time-independent COD removal. The total COD removal efficiency reached 99.5%, and the system proved able to eliminate shock COD loads, as indicated by the concentrations of sludge and volatile fatty acids. Complex changes of phenolic compounds are suspected in anaerobic digestion system, and are investigated further.

  • Description: One of the conference strategies that I found particularly valuable was that of the "syndicate teams" who met regularly to speak on focused topics. Delegates signed up for the topic they were interested in and stayed with that group for the duration of the conference. The list included topics such as the status of journalism education in the academy; the role of journalism in changing the media; adapting journalism education to a digital age, etc.
